The effect of utility model and effect
The connection precast beam of pre-buried shear key provided by the utility model, has: two precast beams, and precast beam has even
Junction and Liang Zong muscle, two precast beams are the most linearly arranged with joint face, and have gap between joint face, and at least two pieces resist
Cutting key, be separately positioned on precast beam, one end of shear key is arranged in precast beam, and the other end protrudes from joint face；A plurality of
Stirrup, stirrup is converted into precast beam shape of cross section by reinforcing bar and beam is indulged muscle and tied up and be disposed between gap；Superelevation
Energy concrete lift, indulges muscle with shear key, stirrup, beam in being filled in gap and pours integral.Because the connection at precast beam
Pre-buried shear key at face, so the connection precast beam of pre-buried shear key that this utility model provides has raising precast beam with existing
Shear resistance at the section of watering joint face, and increase the beneficial effect connecting precast beam globality.
Accompanying drawing explanation
Fig. 1 is schematic diagram at the connection precast beam joint face of pre-buried shear key in embodiment of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, with
Lower embodiment combines the connection precast beam of the pre-buried shear key that this utility model is related to by accompanying drawing and is specifically addressed.
Fig. 1 is the connection precast beam junction schematic diagram of pre-buried shear key in embodiment of the present utility model.
As it is shown in figure 1, the connection precast beam 100 of pre-buried shear key has: precast beam 10, shear key 20, stirrup 30 and
Ultra-high performance concrete LIFT 40.
Two precast beams 10, precast beam 10 has joint face 11, and joint face 11 is provided with the pit of indent, the degree of depth of pit
It is coarse for 50mm, two sides of the through precast beam of pit 10, and the surface of joint face 11.
Two precast beams 10 are linearly arranged relatively with joint face 11, and leave gap 300mm between joint face 11.
Being respectively arranged with at the top of precast beam 10 and bottom that roof beam indulges muscle 12, bottom beam indulges muscle 13, roof beam indulges muscle
